i have some si's rims i might be picking up but i have a question first........

i have a 90 hatch dx that is lowered (cut springs from previous owner) and is sitting on the stock 13's. these si's are 15's as we all know and the tires that are already on them are like 205/55/15's or some shit......i don't know jack about tire sizes and what not and i won't have the chance to "try them on" so what do you guys think?? would they rub like hell???? i am going to put new shocks/struts/springs pretty soon which leads to the other question.....what is a good combination for this? thanks for your input!
